"Come on, be careful." Bai Duxiao took Liu Yu back to her mansion.

Bai Duxiao really wanted to be alone with Liu Yu, and this time she could finally get her wish, pretending to be very calm on the surface, but she was about to turn over in her heart.

Liu Yu took the porcelain outside and found some sterling silver jewelry.

Bai Duxiao stood aside, looking at Liu Yu, staring at Liu Yu all the time, not wanting to transfer from her body at all. Twilight swallowed softly, and the voice woke him up, he couldn't do that.

Bai Duxiao understands that Xie Shenming's person, he must not move, and he cannot have any ideas. They can only watch indifferently, but they cannot do anything.

Lin Mo's immature face, coupled with Liu Yu's unfamiliarity that has not faded, made Bai Duxiao feel just right.

Liu Yu threw the silver into the porcelain jar, and the silver immediately reacted with nitric acid, because the reaction was relatively slow, there was no way to heat it, so he could only wait patiently for this step. 2HNO3+Ag→AgNO3+NO2+H2O。 I brought a wooden basin, poured hot water, put the porcelain in, and after the reaction, a very dangerous nitrogen dioxide gas began to be produced.

Bai Duxiao pulled Liu Yu away and stood next to her, afraid that if Liu Yu had another accident, she would be abolished.

The porcelain bottle was shaken, the bottle was obviously very hot, and after the paws were burned, sprinkled with some cumin, and a bottle of snowflakes, brave the world!!

"This is nitrogen dioxide gas?" Liu Yu looked at the gas coming out, and asked Bai Duxiao by the way.

"Well, when the gas is a little lighter, lower the temperature to zero degrees Celsius, and then filter it." Bai Duxiao said.

"Okay." Liu Yu nodded.

After the gas faded a little, Liu Yu took a piece of cloth and put it aside. "How do you cool down?" Liu Yu took out the porcelain, twisted his head very seriously, and looked at Bai Duxiao with a side eye.

"I cultivate the fire department, Xie Shenming and Xia Jingming too, it seems that only Chen Yici and Ji Xingxi are in the ice department, I will go to find dust Yici." Bai Duxiao hesitated for a while, she was actually quite reluctant to talk to Chen Yici alone, and Chu Xu should have said a lot about herself.

"Okay." Liu Yu nodded, from Bai Duxiao's point of view, because Bai Duxiao was much taller than Liu Yu, he looked down at Liu Yu when he stood close, and Liu Yu looked a little bowed and pouted. Bai Duxiao was stunned for a moment, thinking that Liu Yu didn't want to let her go, so she gently rubbed Liu Yu's hair, which was very thin and soft.

In fact, Liu Yu was just thinking about the full set of methods for silver nitrate solution, and then was inexplicably rubbed by a big hand.

Bai Duxiao successfully brought Chen Yici over, and Chen Yici was also very enthusiastic to help them. As for Chu Xu~ I definitely don't want my daughter-in-law to come into contact with other men, even if Bai Duxiao looks like a little O, she is also a man.

"Why is it so slow?" Liu Yu saw Bai Duxiao and Chen Yici coming over, he was a little anxious, it was nearly an hour, why could he be so slow.

Bai Duxiao was embarrassed to answer, the voice she heard and the picture she saw kept coming to mind. The thought of this made me blush involuntarily, and I tried to forget about it, but it was impossible.

When Bai Duxiao was looking for dust, she was about to push open the door of Chenyici's room directly, "Hmm~" and "uhhhhh I thought of the embarrassment of seeing such a picture, so I kept eavesdropping outside the door, and I didn't dare to enter, and I couldn't knock on the door to disturb people.

Inside the house, Chen Yici was half-lying on the bed, supporting himself with both hands, stepping on the bed very hard with his feet, his legs were very big, his face was red, and his breathing was very heavy. Chu Xu was on the bed, his legs pressed on Chen Yici's legs, and he simply opened them all directly, and Chen Yici's flexibility was very good. The legs are open as if they were sitting cross-legged, except that the soles of the feet are facing each other. Chu Xu didn't dare to press too hard, for fear that Chen Yici wouldn't be able to stand it anymore, so Chen Yici raised his head and didn't look at the next room.

"Relax, it's not the first time." Chu Xu's voice was very gentle, and a little comforting.

"Whew~" Chen Yici couldn't speak, and he was short of breath and had no time to speak.

Chu Xu smiled evilly, buried his head down, supported himself with one hand not to press too hard, and held the bottom of the dust with the other.

"No, no." Dust also said from his hard breath.

How could Chu Xu listen to Chenyi's words, sucked, licked it with his tongue by the way, and began to use his hand to exert force. Looking up at Chen Yici, Chen Yici's whole body was hot, looking at the ceiling, and letting Chu Xu fiddle.

"Let's start, it's too slow." Chen Yici was a little dissatisfied.

"There is growth." Chu Xu smiled and went to pick up the clothes on his body, and put his arms on Chu Xu's neck.

Chu Xu didn't dare to push too hard at first, afraid that he would hurt his little baby again.

But it turns out that the dust is only so cool that it flies.

"I love you." Chu Xu let Chen Yici turn over, and Chen Yici, who was kneeling there, could hold up his hands at first, but his physical strength was slowly exhausted. Just pouted his buttocks, put his arms in front of him, and just lay there on his stomach.

"I, I love you too." Chen's voice was very unsteady and a little trembling.

Bai Duxiao listened to it for nearly half an hour or so, and the two of them were almost over at that time.

The beautiful picture is over!

"Hurry up and cool down." Bai Duxiao didn't want to say more, and after finishing speaking, she was quickly passed.

"Okay." Chen Yici smiled and began to cool down with the ice system.

After a while, Chen Yici began to ask, "Okay?" ”

"Alright, alright." Liu Yu saw that there were already crystallized objects in the porcelain.

"Thank you so much." Liu Yu smiled at the dust, and smiled very gently, which Bai Duxiao had never seen.

"It's fine." Chen Yici took a few steps back, but did not leave, and patted Bai Duxiao on the shoulder when he saw that Bai Duxiao had been being passed. Bai Duxiao, who was immersed in that beautiful picture, was startled, "Yo." Seeing Bai Duxiao being scared like this, Chen Yici was a little scared.

Liu Yu picked up the porcelain bottle, the cloth was stacked very thickly, and then began to pour it little by little, the cloth absorbed water, and what was left was some transparent lenses, which could be used to make silver nitrate.

"Step 1 complete!" Liu Yu smiled happily, his eyes almost narrowed into a slit, happy like a fool. It's the first time I've made silver nitrate solution under such difficult conditions, and I'm so excited to solve the case.
